Moisture And Temperature Ageing On htpb Based Propellants Binder

Macromolecular Symposia, Volume 414, Issue 3, June 2025.
Abstract This study reports the impact of temperature, oxygen, and humidity ageing on the mechanical properties of a crosslinked hydroxy‐terminated polybutadiene (HTPB) network. Its mechanical behavior is described using a classical Mooney‐Rivlin model and shows a slight crosslinking reaction possibly due to oxidation of HTPB.
